🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Chloroquine is a weak base that accumulates in the acidic food vacuole of the malaria parasite. Inside the vacuole, it becomes protonated and cannot diffuse back out, leading to an increase in pH. This alkalinization interferes with the parasite's ability to detoxify heme, a byproduct of hemoglobin digestion. The toxic heme accumulates and causes oxidative damage to the parasite's membranes, ultimately leading to parasite death. In autoimmune conditions, chloroquine is thought to modulate immune responses by inhibiting antigen presentation and reducing the production of pro-inflammatory cytokines, although the exact mechanism is not fully understood.
